In IELTS General Training Writing Task 1, the test-taker is required to write a letter in response to a given situation. The task specifies three bullet points that must each be addressed within the letter. According to the official IELTS guidelines, the minimum length is 150 words, and the task is recommended to be completed in approximately 20 minutes. Register — the degree of formality appropriate to the context and the relationship between writer and recipient — is the single most important variable in General Training Task 1. A formal letter written in an informal tone, or vice versa, results in a direct Task Achievement penalty regardless of language quality.

1. The Three Letter Types and Register

IELTS General Training Task 1 letters fall into three register categories. Identifying the correct one before writing is the most important decision you will make.

RegisterWho you are writing toSalutationSign-off
FormalUnknown person / company / authority / organisationDear Sir or MadamYours faithfully
Semi-formalA known professional contact (landlord, teacher, manager by name)Dear Mr/Ms [surname]Yours sincerely
InformalA friend or family memberDear [first name]Best wishes / Kind regards
Register consistency is assessed under Task Achievement. A single sentence in the wrong register — for example, writing “Thanks a lot!” in a formal complaint letter — is enough to reduce your Task Achievement band. Once you have identified the correct register, maintain it from salutation to sign-off without deviation.

2. How to Identify the Correct Register

Follow this three-step process every time:

  1. 1

    Step 1: Who are you writing to?

    A company or unknown person = Formal. A named professional contact (landlord, manager) = Semi-formal. A friend or family member = Informal.

  2. 2

    Step 2: What is the nature of the situation?

    A complaint to a business = Formal. A request to your landlord = Semi-formal. A personal invitation = Informal.

  3. 3

    Step 3: What does the question say explicitly?

    If it says 'write to a friend', the register is informal. If it says 'write to a company', the register is formal. The question always provides a clear signal.

SituationRecipientRegister
Complaint about a faulty productCompany customer serviceFormal
Request to extend a rental contractLandlordSemi-formal
Apologising for missing an appointmentYour managerSemi-formal
Inviting someone to an eventA friendInformal
Asking for information about a college courseA college admissions officeFormal
Recommending a place to visitA friendInformal
Requesting a work referenceA former employer you know wellSemi-formal
If in doubt between formal and semi-formal, choose formal — it is the safer choice under Task Achievement. An overly formal letter is less likely to be penalised than an inappropriately casual one.

3. Letter Structure

Every Task 1 letter — regardless of register — follows the same fundamental structure. The content of each section varies by register, but the sequence remains constant.

SectionContentRecommended words
SalutationDear Sir or Madam / Dear Mr Smith / Dear John3–5 words
Opening sentenceState the purpose of the letter clearly and specifically.20–25 words
Body paragraph 1Address bullet point 1 fully — do not merge with bullet 2.30–40 words
Body paragraph 2Address bullet point 2 fully.30–40 words
Body paragraph 3Address bullet point 3 fully.30–40 words
Closing sentenceForward-looking statement, expression of hope, or request for response.15–20 words
Sign-off + nameYours faithfully / Yours sincerely / Best wishes, then your name.5–8 words
Weak opening sentence:“I am writing to you today to...” — this wastes words and sounds generic. Instead, state the specific reason immediately: “I am writing to complain about the incorrect charge applied to my account on 14 March 2026.” A specific, purposeful opening sentence demonstrates both Coherence and Task Achievement.

4. Opening and Closing Phrases by Register

Knowing register-appropriate phrases for different functions is essential for maintaining consistency throughout the letter. The table below provides reference phrases for six key communicative functions across all three registers.

PurposeFormalSemi-formalInformal
Stating purposeI am writing with regard to... / I am writing to formally complain about...I am writing to ask whether... / I wanted to let you know that...I just wanted to drop you a line about... / I'm writing to tell you some exciting news...
Making a requestI would be grateful if you could... / I would appreciate it if...Could you please let me know...? / I would appreciate your advice on...Could you do me a favour and...? / I was hoping you could help me with...
ApologisingPlease accept my sincere apologies for... / I sincerely apologise for any inconvenience caused.I'm sorry for the short notice, but... / I apologise for not getting in touch sooner.I'm really sorry about... / I feel terrible about missing...
Providing informationI wish to bring to your attention that... / I am writing to inform you that...I thought you should know that... / I wanted to update you on...Just so you know,... / I wanted to let you know that...
Expressing hope / forward-lookingI look forward to hearing from you at your earliest convenience.I hope to hear from you soon. / I look forward to your reply.Hope to hear back from you soon! / Can't wait to catch up!
Closing sign-offYours faithfully, [Full name]Yours sincerely, [Full name]Best wishes, / Kind regards, [First name]
Vary your vocabulary within the correct register rather than repeating the same phrases. If you use “I would be grateful if” in one paragraph, use “I would appreciate it if” in another. Lexical variety within a register demonstrates range without sacrificing appropriateness.

5. How to Address All Three Bullet Points

Each bullet point in the task represents a required element of the letter. Missing one — even partially — results in a direct Task Achievement band reduction. The rule is simple: one paragraph per bullet point, always.

Before writing, number the three bullet points on your question paper: 1, 2, 3.

Write one key idea for each bullet as a brief planning note.

Use each note as the topic sentence for its respective body paragraph.

After writing, check off each bullet point to confirm it has been fully addressed.

Most common error: Merging two bullet points into one paragraph. This typically happens when the test-taker runs out of time or ideas. Even a brief, direct paragraph addressing just one bullet point is better than a longer paragraph that tries — and fails — to cover two.

6. Sample Letters — All Three Registers

Formal Letter

Task: You recently bought a piece of electrical equipment from a shop. When you got home you found that it did not work properly. Write a letter to the store manager. In your letter: describe the item you purchased / explain what the problem is / say what you would like the store to do.

Dear Sir or Madam,[Formal — unknown recipient]

I am writing to draw your attention to a faulty item I purchased from your Oxford Street branch on 8 April 2026 and to request an urgent resolution.[Clear purpose — formal register]

The item in question is a Duronic DP5 food processor, which I purchased for £89.99. I have retained the original receipt as proof of purchase should it be required.[Bullet 1: describes item]

Upon returning home, I discovered that the motor failed to engage when the appliance was switched on. I attempted to use the device on three separate occasions, each time following the manufacturer's instructions precisely, but the result was the same on each occasion.[Bullet 2: explains the problem]

I would be grateful if you could arrange a full refund at your earliest convenience. Should a refund not be possible, I would be willing to accept a replacement item of equivalent value, provided that it has been tested prior to dispatch.[Bullet 3: states desired action]

I look forward to your prompt response on this matter.[Formal closing]

Yours faithfully,
A. Rahman[Correct sign-off for Dear Sir or Madam]

Semi-formal Letter

Task: You are renting a flat. There is a problem with the heating system in your flat. Write a letter to your landlord. In your letter: explain what the problem is / describe how it is affecting you / ask your landlord to take action.

Dear Mr Patel,[Semi-formal — known by name]

I am writing to inform you of a significant issue with the heating system in my flat at 14B Greenfield Road, which requires your attention as soon as possible.[Clear, polite opening]

The central heating has not been functioning correctly for the past ten days. The boiler activates normally but fails to distribute heat through the radiators, which remain completely cold regardless of the thermostat setting.[Bullet 1: explains the problem]

As a result, the temperature inside the flat has dropped considerably, which has made it difficult to sleep comfortably and has begun to affect my health. I have been experiencing headaches and fatigue, which I attribute to the damp and cold conditions.[Bullet 2: impact on the tenant]

I would appreciate it if you could arrange for a qualified engineer to inspect the boiler at your earliest convenience. Could you please confirm by email when an appointment would be possible?[Bullet 3: request for action]

I hope to hear from you shortly.[Semi-formal close]

Yours sincerely,
D. Sharma[Correct — 'sincerely' used with named salutation]

Informal Letter

Task: You have recently moved to a new city. Write a letter to a friend who also lives in the same city. In your letter: tell them about your new home / explain what you like about the city / suggest a time to meet up.

Dear Priya,[Informal — first name]

I can't believe we're finally living in the same city! I've been meaning to write ever since I arrived last month, so here I am at last.[Natural, friendly opening — contractions appropriate]

I'm renting a small but really lovely flat in Brixton, just a five-minute walk from the tube station. It's a bit noisy compared to where I lived before, but I've already started to love the character of the neighbourhood — there's a brilliant market just around the corner that I visit most weekends.[Bullet 1: new home]

As for the city itself, I honestly wasn't expecting to fall for it this quickly! What I love most is how much there is to do at any time of day — the museums, the parks, the food scene. I went to Borough Market last Saturday and I think I might have spent half my weekly budget there, but it was absolutely worth it.[Bullet 2: what they like about the city]

We absolutely have to catch up soon! Are you free any evening next week? I was thinking we could try that Ethiopian restaurant on Coldharbour Lane that you mentioned last time we spoke.[Bullet 3: suggests meeting]

Can't wait to see you!

Best wishes,
Sara[Informal sign-off]

Examiner note on all three letters

All three letters demonstrate consistent register from salutation to sign-off, address all three bullet points in separate paragraphs, and use register-appropriate vocabulary and grammar throughout. The formal and semi-formal letters use no contractions; the informal letter uses them naturally to establish tone. All three exceed 150 words without unnecessary padding.

7. Common Mistakes to Avoid

Wrong register: Using formal language in an informal letter, or casual language in a formal complaint — this is the single biggest Task Achievement error in General Training Task 1 and results in a significant band penalty.
Not addressing all three bullet points: Missing even one bullet point is penalised under Task Achievement regardless of language quality. One undeveloped sentence per bullet point is better than omitting it entirely.
Writing fewer than 150 words: The examiner checks the word count. Under 150 words is a direct Task Achievement penalty. Aim for 160–175 words.
Using 'Dear Sir' when you have been given a name: If the task says your landlord is called 'Mr Williams', you must write 'Dear Mr Williams' — not 'Dear Sir'. Using the wrong form of address signals a failure to read the task carefully.
Using 'Yours sincerely' after 'Dear Sir or Madam': 'Dear Sir or Madam' must be paired with 'Yours faithfully'. Using 'Yours sincerely' with an anonymous salutation is a standard Task Achievement error that is easily avoided.

8. Frequently Asked Questions

What is the difference between Yours faithfully and Yours sincerely?+
'Yours faithfully' is used when you begin with 'Dear Sir or Madam' — when you do not know the recipient's name. 'Yours sincerely' is used when you begin with the recipient's name (Dear Mr Smith, Dear Ms Johnson). A useful memory rule: if you do not use a name at the top, do not use 'sincerely' at the bottom.
Do I need to write my address at the top of the IELTS letter?+
No. Begin directly with the salutation (Dear Sir or Madam, Dear Mr Smith, Dear Sarah). Writing an address wastes words and time without contributing to your band score.
What if I am not sure whether to use formal or semi-formal register?+
Choose formal. A formal letter written about a semi-formal situation is safer than a semi-formal letter that slips into informality. Examiners reward consistency of register. If the question mentions writing to 'a manager', 'a company', or 'an authority', choose formal.
How many paragraphs should a Task 1 letter have?+
A standard Task 1 letter should have five sections: salutation, an opening sentence (stating purpose), three body paragraphs (one per bullet point), a brief closing sentence, and the sign-off. Each body paragraph should address exactly one bullet point — never merge two bullet points into one paragraph.
Can I use contractions in a General Training letter?+
Only in informal letters. Contractions (I'm, I've, can't) are appropriate in an informal letter to a friend or family member. In formal or semi-formal letters, contractions are inappropriate and reduce your Task Achievement score. Write 'I am', 'I have', 'cannot' in all formal and semi-formal contexts.
